- part of this specification.

The objects of my present invention, which relates to the practical, convenient and economical production of doubled belts or card-fillets in which to set the teeth for making cardclothing, are to provide a simple and desirable mechanismfor uniformly and rapidly laying and cementing together separate plies or strips of .leather or material to form a single belt or fillet of any desired length, and afford facilities for the continuous doubling, cementing, and finishing of doubled fillets or belts. These objects I attain by mechanism substantially such'as illustrated or organized for operation as described, the particular subject-matter claimed being hereinafter definitely specified.

In the drawings, Figure l is a plan view of my improved machine for doubling and cementing fillets or belts. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a top view, 011 larger scale, of the scraper for removing surplus cement. Figs. 4: and, 5 are front views of the adjustable guides. Fig. 6 shows arrangement of mechanism for doubling, trimming, and finishing fillets or belts by continuous process. Fig. 7 is a plan view of an edge-trimming device. Fig. 8 is a view ofa piece of doubled fillet or belt such as produced by the means hereinafter described.

My improved cementing and doubling mechanism is constructed of the following named parts, arranged for operation in the manner set forth.

A denotes the roll for applying the cement. It is mounted in bearings on' a suitable frame, B, and is provided with a driving pulley or gear, a, for effecting its revolution. The lower side of the roll A runs in a pan or reservoir, 0, that contains the glue or other suitable oeunderneath the reservoir 0. A scraper or cl earin g-bar D, is arranged in connection with the roll A, for removing surplus cement from the face and sides of said roll. Adjustable plates (1 are arranged on said scraper-bar, by means of which the width of the cementedsurface and the quantity of cement applied can be regulated according to the requirements of the work.

E indicates a roll mounted at the opposite end of frame B, which serves as a bed for the pressure-roll F, retained in slotted bearings above the roll E in a manner to permit of its pressing on the material as it passes .between the rolls. Roll E may be made hollow and be fitted with steam connection for heating it from the interior; or it can be made solid. as

preferred.

Guides G H I K are arranged, as shown, for directing the strips that form the belt or fillet into and through the machine. indicated in the drawings. Said guides are made, as shown in Figs. 4 and 5, with laterally-adjustable side disks or pieces, h, which can be moved toward or from each other to.

The course is I accommodate different widths of belt, and with bars '5 to inclose the spaces 6 for the belts. Guide I is made with two spaces, 0 c, for the passage of the strips of material m m and to bring them uniformly together between the pressing-rolls E F. V y A scraper-bar, L, is provided between the rolls A and E for spreading or leveling the cement and clearing offany surplus from the surface of the belt on. This scraper may be made with a corrugated edge, as shown in Fig. 4, so as to work the surface in fine ridges. A guide-baig'f, serves for retaining the belt down upon the scraper L and roll A. The two bands of material m m are entered into the machine at the different guides G and H, one passing over the roll A and scraper L to the guide I and pressing-rolls E F, the other passing beneath the reservoir 0, through the guide K, and thence to the guide I and pressing-rolls E-F. The rollArevolves in opposite direction to the movement of the strip m, so that the cement brought up by the roll is wiped off from the roll-face onto the belt-strip m.

This is then more evenly and uniformly spread by the bar L, and the two strips m and m are brought together at the guide I, and the cemented surface of the strip 722 is pressed firmly to the'strip'm by the action of the rolls E F, causing the two strips to unite and form the belt or fillet M.

In Fig. 6 is shown an arrangement of mechanism for making and finishing doubled fillets or belts by my continuous process. These belts or fillets may be made from short thin pieces of stock, such as are useless for the purposes of cardsetting, except when doubled and cemented together andto render the operation of doubling, cementing, and finishing sufiiciently rapid, convenient, and'economic for practical purposes, I have devised the within described method of manufacture. The stock is split to a uniform thickness of about one-half the required thickness of the finished belt. It is cut into strips the required width and the ends scarfed to make the lateral joints 0. The scarfed ends of these short pieces are cemented together to form the long strips m m. These strips are passed between series of bars N, or devices for giving friction or tension on the strips m m, which are then drawn into and through the doubling and cementing appara tus, where the two strips m m are united, in the manner hereinbcfore described, to form the doubled card-fillet or belt M. The parts are placed together, so that the grain surface of the leather will be outward at both sides of the belt. The belt or piece M is, after leaving the pressing-rolls E E, carried for a sufficient distance to permit the cement to set or harden suffieientlyto withstand the subsequent operations, it being supported by drums I or other suitable devices. It is then passed through an edge-trimming device, R, which trims and evens both the edges, as at t t, and reduces the fillet to the required width. It is then passed ,through a set of polishing-rolls, S, which smooth off and finish the surfaces, after which it is rolled into coils T, of any desired size, and is ready for use.

The process is continuous, and the successively-described operations are simultaneously performed as the belt or fillet moves forward with a continuous motion.

The mechanism used for trimming the edges may be of any suitable construction that will effect the desired result as the belt moves forward. The polishing-rolls B may also be of any suitable form adapted for the purpose, as I do not claim the details of construction of said trimming and polishing mechanism.

The cementing and doubling mechanism may, if desired, be employed separate from the other devices, and may be used for making machinery belts as well as for card-fillet- 111 Among the advantages incident to my i11- vention it may be mentioned that the doubling can be performed more rapidly than by the ordinary methods, the cement or glue is spread more uniformly and thoroughly on the sur faces, and the two pieces are therefore caused to adhere to each other with greater tenacity, while a less quantity of cement is required for a given quantity of stock than in ordinary cases, thus making a saving of about twenty-five per cent. in the costof cement. Another advantage accruing from the use of less cement is that the fillet or belt has a more uniform pliability, and is better adapted for use than when the cement has been spread on with a brush. The doubling, cementing, and finishing can by my process and mechanism be done with less labor, trouble, and expense,while ahandsomer and more perfect product results than by the means heretofore in use for doubling, cementing, and finishing fillets or belting.

\Vhat I claim as of my invention, and desire to secure by Letters Patent, is

1. A mechanismfor doubling and cementing fillets or belts, consisting of a roll for ap plying the cement, a spreading bar or device for leveling off the surface and removing surplus cement, a pair of pressing rolls, and guides for separately directing the strips of material into the machine, and guiding them together between the 1)l6SSl11g-1O]lS, substantially in the manner set forth.

2. In a machine for cementing fillets or belts, the combination of the reservoir C, the roll A, the adjustable clearer -plate D, and the guides G, f, and I, substantially as shown and described.

3. In a machine for doubling and cement- 1 ing fillets or belts, the combination of the roll. A, reservoir 0, clearer plate D, leveling- ,scraper L, presser-rolls E F, and a series of guides for directing the strips of material into and through the machine, substantially as and for the purpose set forth.

t. I11 a machine for doubling and cementing fillets or belts, the combination, with the cement-applying roll A and pressing-rolls E F, of guides having laterally-adjustable side plates, substantially as and for the purpose set forth.
